I've been using wine-staging 2.19 with DOOM 2016 and GTA 5. In both of those
games, looking around using the mouse will sometimes get stuck until I move the
mouse faster out. When going to the game menu, I can see that the cursor is
positioned at one end of the screen. When I place the cursor in the middle of
the screen and go back ingame, the mouse will move freely until I hit one
border of the screen with the cursor again.

It happens with both of these games. I tried DOOM with wine-staging 2.3 and hit
the same issue. Switching between GNOME and Xfce doesn't help.
